We too had this issue with our CI. The problem was the xvfb-run. When
the build finished, this process was still running and when another
build ran, it caused a out-of-memory error and hung our CI. We found
out that the command used to kill xvfb-run, wasn't actually killing
the process on CI and creating a zombie process.
So I added the following profile to the parent pom:
.....
<profiles>
<profile>
<id>unix</id>
<activation>
<os>
<family>unix</family>
</os>
</activation>
<build>
<plugins>
<plugin>
<artifactId>maven-antrun-plugin</artifactId>
<executions>
<execution>
<id>kill-xvfb</id>
<configuration>
<tasks>
<exec executable="killall">
<arg value="-s" />
<arg value="9" />
<arg value="Xvfb" />
</exec>
</tasks>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
</plugin>
.......
Then in the child pom I added:
.....
<plugin>
<artifactId>maven-antrun-plugin</artifactId>
<executions>
<execution>
<id>kill-xvfb</id>
<phase>verify</phase>
</execution>
</executions>
</plugin>
...
And that did it for us. It was only hanging only on CI which is a unix
machine, so the profile is only for unix machines.
Hope this helps...
